[libvirt] [RFC PATCH v2 00/18] Introduce vGPU mdev framework to libvirt

[Erik Skultety]

since v1:
- new <hostdev> attribute model introduced which tells libvirt which device API
should be considered when auto-assigning guest address
- device_api is properly checked, thus taking the 'model' attribute only as a
hint to assign "some" address
- new address type 'mdev' is introduced rather than using plain <uuid> element,
since the address element is more conveniently extendable.
- the emulated mtty driver now works as well out of the box, so no HW needed to
review this series --> let's try it :)
- fixed all the nits from v1
